Their research shows that a toxin in Yersinia pestis, the bacterial agent of plague, targets and inhibits the protein pyrin. The inherited autoinflammatory disease Familial Mediterranean Fever (FMF) is caused by mutations that lead to continuous activation of pyrin.http://medicalxpress.com/news/2016-09-treatment-common-autoinflammatory-disease.html

Diseases, Conditions, SyndromesMon, 02 Nov 2015 11:04:36 ESTnews365684664Staphylococcus aureus Achilles' heelStaphylococcus aureus is both a transient skin colonizer and a formidable human pathogen, ranking amongst the leading causes of skin and soft tissue infections, as well as severe pneumonia. Scientists attempt to work out new strategies to fight against this pathogen, of which numerous strains are now resistant to antibiotic treatments. One of the bacterium's most impressive weapons is α-toxin, which provokes the destruction of human cells. An international project led by the Stanford University School of Medicine in California, in collaboration with the University of Geneva (UNIGE) in Switzerland, allowed to identify the components of our cells that modulate the virulence of this toxin, in particular the PLEKHA7 protein. By eliminating expression of the latter, cells gained the ability to recover from α-toxin injury, and mice lacking PLEKHA7 exhibited improved healing from bacterial skin infection as well as enhanced survival of pneumonia.
